Have you ever looked at a body of water and wondered if it was a lake or a pond? Here’s everything you need to know to determine if a body of water is a lake or a pond.
Lakes versus ponds

A body of water is called a pond if it is small and closed, and the lake is large and open. There are many lakes in the world, although there are more ponds than lakes. Some lakes can be over 4,000 feet deep, while most of the ponds are shallow. Many people use the word “lake” to describe any body of water that does not differ in size and depth. The two terms are often used interchangeably because there is no standardization on the matter.
Here are some steps to help you distinguish a lake from a pond:
1. Depth: The lake is usually deeper than the pond.
2. Form. The lake is also usually oval in shape with peninsulas, while ponds usually have rounded edges.
3. Nature: Lakes are mostly freshwater, but may contain some salt water, while ponds are freshwater.
Lake | Pond | |
Depth | 20-4000 feet | 4-20 feet |
Trade point | Open | Closed |
The size | 200+ acres | <200 acres |
Here are some more ways to find out if you are looking at a lake or pond:
Definition of lakes and why there is no standardization
The National Oceanic and Atmospheric Administration (NOAA) has made the following recommendations to differentiate the two bodies of water.
- A pond is a body of water less than 0.5 acre (150 square meters) in area or less than 20 feet (6 meters) deep.
- A lake is defined as a body of water over 1 acre (4,000 m²), although its size is not a reliable indicator of its water quality.
One of the reasons it is difficult to follow any standardization is because the lakes and ponds were named by the people who called them did not know what to call them. For example, settlers across America arbitrarily used the name of a lake instead of a pond to refer to bodies of water. In Vermont, Lake Echo is 11 feet deep and Conway’s Pond is 80 feet.

Difference between lake and pond
With so many lakes, ponds and streams in the world, it may not be very clear which one is which. The lake does not have a standard depth scale.
A pond is formed by a slow, gradual excavation from, for example, a swamp or swamp. You will find pond lilies in ponds, although water lilies and reeds are more common in lakes. The initial layer of sand and silt surrounding the pond gradually erodes, exposing the bottom. This bottom layer is similar to a swamp or swamp and is usually a thin layer of rock with several layers of vegetation. Many ponds have an underwater garden with aquatic plants and trees. On the surface of the ponds, there are areas where the top layers of dirt, rocks and vegetation have worn away, exposing the underlying soil layer of the pond.
The easiest way to tell the difference between a pond and a lake is to find out their depth. A small pond is usually 4 to 20 feet deep, while lakes are usually over 20 feet deep.
In most lakes, the deepest spot is known as the “last straw” or “end of the lake”. Water in a small pond or natural spring will have no depth. The lakes are deep enough for plants to not grow at the bottom, but the ponds are shallow enough for plants to thrive. The lakes are often fed and drained by rivers and streams.
The reason the two terms are often used interchangeably
Small ponds are often called lakes and vice versa. Sometimes it can be difficult to distinguish a lake from a pond because there is little difference. A pond is sometimes called a lake if it is small and closed, and the lake is large and open. One difference between lakes and ponds has to do with the land surrounding the pond. There are three questions you can ask yourself to determine if you are looking at a lake or a pond.
- Does the light reach the bottom of the deepest point in the body of water?
- Are there only small waves in the reservoir?
- Is the body of water relatively uniform in temperature?
What kind of life do you find in a lake or pond?
The lake is home to many different types of plants and animals. Some common plants found in lakes include cranberries, algae, naiados, and even horsetails. The daily life of animals is found in lakes such as mussels, dragonfly larvae, water buffalo, herons and ducks. Both species are not always found in the same body of water. On the other hand, weeds such as tall grass and ferns growing at the water’s edge are much more common in ponds. Aquatic birds often rest in the grassy areas that grow along the water’s edge. Most fish prefer the pond to be muddy and deep enough to hide in when not actively feeding.
